Bao nhiêu tuổi? — Talking about age

What you will learn

Age is not just a number in Vietnamese. It can help speakers decide whether to use anh, chị, em, cô, chú and other relationship terms. This lesson teaches the language of age together with that social context.

1. ... bao nhiêu tuổi?

• Bạn bao nhiêu tuổi? — How old are you?
• Anh bao nhiêu tuổi?
• Chị bao nhiêu tuổi?

Tuổi means age/years of age in this pattern.

2. Saying your age

• Tôi 25 tuổi. — I am 25 years old.
• Em 20 tuổi.
• Anh 32 tuổi.

Notice that Vietnamese does not need là: say Tôi 25 tuổi, not Tôi là 25 tuổi.

3. Bao nhiêu is broader than age

Bao nhiêu asks “how many/how much” in many contexts:

• Bao nhiêu tuổi? — how old?
• Bao nhiêu tiền? — how much money?
• Bao nhiêu người? — how many people?

4. Why age matters to xưng hô

If two adults do not know how old the other person is, choosing anh/chị/em may involve an estimate. Once age becomes clear, the pair can become easier to choose.

This does not mean age mathematically determines every pronoun. Relationship, role and social setting also matter.

5. A short conversation

Lan: Anh bao nhiêu tuổi?

David: Anh 31 tuổi. Còn em?

Lan: Em 27.

David: À, vậy anh lớn hơn em bốn tuổi.

Lan: Dạ.

6. Natural speech may omit tuổi

Once the topic is clearly age, someone may answer:

Em 27.

The word tuổi is understood from context.

7. Should you ask everyone’s age?

No. A question can be grammatically correct but socially inappropriate.

Age questions can be relatively common in Vietnamese interaction because age helps establish terms of address, but comfort varies by person, generation, setting and relationship.

8. Older and younger

• lớn hơn — older / greater than
• nhỏ hơn — younger / smaller than
• hơn ... tuổi — ... years older/younger depending on sentence

You will study comparison more systematically later.

9. Useful vocabulary

• tuổi — age / year of age
• bao nhiêu — how many/how much
• lớn hơn — older/bigger than
• nhỏ hơn — younger/smaller than
• bằng tuổi — same age
• năm nay — this year

10. Vietnam in real life

Age can be socially useful because Vietnamese address terms encode relative position. But learners should not turn that into a rule that they must ask every stranger’s age. Observe the setting and follow the other person’s lead.

11. Common beginner mistakes

• Using là before age.
• Thinking age alone determines every form of address.
• Assuming a culturally common question is appropriate in every situation.

Try it

1. Say your age.
2. Ask someone’s age using chị.
3. Say “I am 30 years old” without using là.
4. Explain why age can affect Vietnamese xưng hô.

Quick recap

Use ... bao nhiêu tuổi? to ask age and ... + number + tuổi to state it. Age matters socially in Vietnamese, but context matters just as much.
